Hybrid Rifle-length 308 Barrels

Criterion’s rifle-length 308 Hybrid barrel is a mid-weight government contour barrel for large frame DPMS pattern rifles. The additional weight around the chamber increases heat absorption and rigidity over conventional designs.

Why 308 Hybrid?

• Added chamber material - increases heat absorption and rigidity
• Mid-weight design - reliably handles high heat while maintaining exceptional performance
• 308 Win M118 LR Match chamber - compatible with both 7.62x51 NATO and .308 Win ammunition; optimized for heavier, longer bullets
• Nitrided - improved barrel life and corrosion resistance without degrading accuracy
• Honed - refines bore for superior uniformity to reduce bullet deformation
• Hand-lapped - essential for accuracy and to minimize fouling
• Polished chamber - reliable extraction and feeding
• Precision-machined barrel extension - safe and reliable feeding

Why Headspace Matters

Purchasing a headspaced bolt is not required. However, Criterion's headspace service guarantees optimal bolt to barrel fitment using premeasured bolts and certified headspace gauges, helping to maximize the performance and function of your build.

Headspace (the critical measurement from the bolt face to the shoulder of the chamber), must be checked for optimal performance and reliability. Proper headspace produces consistent chamber pressures and seating depths which results in increased accuracy and reliability, while reducing wear and tear on internal parts and components.
